Subject [jira] Commented: (HIVE-134) job conf being passed to serde (initialize)
Date Mon, 08 Dec 2008 20:14:44 GMT

    [ https://issues.apache.org/jira/browse/HIVE-134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12654552#action_12654552

Joydeep Sen Sarma commented on HIVE-134:
----------------------------------------

i disagree.

the whole idea with serde is that these are opaque to hive except for the functional interfaces
exposed via the serde interface. as u can see - the interfaces don't currently have any information
about 'options' that the serde may use. Hence we pass the jobconf to the serde so that it
can get whatsoever it pleases.

i don't see the point of this jira. we are trying to create a more strongly coupled system.
in order to do what Raghu is saying - now we will need another interface in the serde to get
the list of required options, and then extract them from the jobconf and then pass those in.
what good will this serve? why are we making it even harder to write serdes?

what real and existing problem are we trying to solve here?

> Currently, job conf is being passed to serde - serde should not need job conf. Anyway,
properties is being passed around which can contain any name/value pairs.
> Once jira-127 is committed, this should be done in a follow-up
